The magnitude of acceleration is the same as the tangerine passes through all windows.
Work Step by Step
The only force that acts on the tangerine after it is thrown is the force of gravity (neglecting air resistance in this problem). The force never changes as long as it's in the air. Based off of the equation a=Fnet/m, we know that the acceleration does not change because the mass of the tangerine and the force applied to it remain constant.
